Be. it known thatA I., PABLO GONZLEZ Grenze,` a `citizen of. the UnitedStates, residing at San Antonio, inthe county otgBeXar andStateof Texas,have, inventedanewand useful Drier, oiiwhichwtlie olloivingis aspeciiicaton.

Th is, invention relates. todryingapparatus particularly design-edf.`for use. in,k reducing, to a dried condition cereals and. the like. thathave been grou-nd; While saturated with Water, The drier is.particularly useful4 in the production of ilounfroincoun, itgheing thepractice,ras4 disclosed.. in Patent-4 No. 1,334,366 `to thoroughlysaturate y,the corn/ or othercereals and*L grinditwhile in itssaturatedj condition.. 'Ifhisrvvet` meal thus produced must,subsequently loefA thoroughly dried prior to beingT reduced to apowdered or flour condition; Thepresent. invention is designed to`drythe Wetmeal prior-to the formationio-tthe-iiour and one ofitsfobjects is to` quickly and", thoroughly drive offthe moistureandat'the Sametime keepthefmatcrial being".v treated l in a constant stateof agitationk so. that. moisture willy be driven from allportion'sthereof.

Aiturthenobject is:A to provide dryingapparatusivhich iscompactandteiiicient, and has improved means foncarrying off the,condensed moisture afterbeing, drivenf-roln the material beingitreated,there being additional means for removing,vaporr from the drier.. p

A. further object is to rovide a` drier whichwillheat; the materia bothalong the center offeach clryingfunit and, also atthe pe# ripherythereof.

A further object; iste provide means for scattering the material`vrwhen; directedi into the drierfso `that itywill be..depositedinsmallparticles audenotv in bulk, thus greatly;` facilis tating. the .dryingoperation...

Referring. to the .gjures ,by characters 'ot reference A` designates'a`supporting structure Preferably made of,` pipes forming standards andconnectingrails and jonrnaled in this;v Structure are superposedparallelshafts 1,2, 3, ande each of which is `formed of pipe. Allotthe.shatsmntionedfare connectedglatone end, to a steam Supply pipe 5having-a suitable valve` Ggvvhile. the; oppo site ends,v of. the pipes;l?, 2f and@v are, con-` nected to a-,drainpipe Each of the shafts l, 2and 3l plug Srseated-Ytlierein'f solas to divide. the. inteigior. ofthej shaft intoja steani containing' portion andA a Water containingr ordraining portion.` The shafts may Vloe connected to tlhjepipes rand Tinany suitable manner so as to permitthem to rotate and at the saine timemaintain tight joints at theirfpoints.otconnection.

This drum 15 is also provided with a steam jacket such. as shown .at11, one or more of the arms of the spiders constituting means forconducting steamfrom the shaft 2 to the steam jacket. One of thesetubular arms'of the drum 415 has been indicated at` 20.A i.

VThe delivery spout 17 servesto direct material into the small end ofanother conical drum 21 mounted on the shaft 3 and which is of the sameconstruction as the drum 10 and has its large open end rotating within adeliveringhead 22. Theoutlet spout 23 ofthis head opens into one lend ofla cylindricalV casing 24 arranged -under the drum 21 and provided witha steam jacket 25 to which steam is applied in any suitable manner fromthe pipe 5, asvthrough aibranch pipe 26. rIhe shaft 4'has a wormconveyer 27 secured to itand that end of the Vcylindricalcasing 24remote from the spout 23 has an outlet 28 adapted to direct driedmaterial into a suitable container 29. @Extending Vfrom the upperportionofthe head 12 is an outlet Hue 30 for vapor-*and opening Vinto this fiueis another outlet flue 31 extending from the topf portion of the casinoror housing 24, the lower portion of this tflue 31 being preferablybranched or forked as showin 5 A blower casing 32 is mounted adjacentthe head 12 and has a hopper 33 opening into one side thereof. Y

A delivery pipe 34 extends'from the outlet of the casing 32 and opensthrough the upper portion ofthe head .12, anda blower, not shown, ismounted in the casing 32 and Vis adapted to suck air through the hopper33 and to discharge it through pipe` 34 into the upperdrum 10. 7,' f

A main drive shaft 35 is journaledonrthe structure A and hasa pulley 36adapted to receive motion, through a belt from a suitable motor, notshown. belt 38 4trans mits motion from thisfpulley to1 thepulley 39 'ofthe'shaft'40 of the blower-. gear 41 rotates with the pulley 36 landmeshes "with a gear 42 vsecured lto the shaft 3. On

this shaft'is attached a sprocket 43 which transmits motion through a'chain 44 toa sprocket 45 secured to a counter shaft 46. Anothersprocket v47 is secured, torthe counter shaft andA transmits ymotionthrough a chain. 48 toa sprocket 49 on the shaft 2.

A third sprocket 50 is securedto the counter shaft :and transmits motionthrough a V'chain 51 to a sprocket 52k on a second counter Shaft 53 ,andmotion is transmitted, from this "the'shaft 3 andtransmits motionthrough achain 53 to a sprocket 59 secured to the shaft 1, there beingan idler sprocket 60 en- .i gaging` the chain 53.

In using the apparatus herein 4described the saturated'meal is fedthrough the hopper 33 into the housing of the blower andthe blower,operating on this-material, throws it into the upperdruni 10 which isrotating` and'scatters itthroughout the area thereof.A The material'thusfscattered will be heated by the wall of the drum andi also by theheat radiating from the steam containing-portion of the shaft 1 andthe'moisture driven ,off in this mannerwillv to a large extent escape byway'oftheflue30 although some of it will become condensed upon vthe head12. This condensed moisture will be gathered upby the spiral collectingmember 14 and directed into the draining end of the shaft 1 from whichitwill flowdownwardly through the pipev '71 'As the drum is inclined thematerial asV it dries will work downwardly t'o the head 12 and bevdischarged through spout 13 into' the second drum 15 along which itwillwork into the third drum 21 and thence into the receivingiend of thehousing or" casing 24where'itwill be engaged by the spiral conveyer andconducted to the outlet 28. As the material passes lsuccessively throughthe drums it will of course' be furtherheated in view of the fact'thateach ofthe drums has a steamjacket and has a central steam containingshaft. j Consequently when the ma# terial is Ydischarged into thecontainer 29 it will bethoroughly dried 'and can'beeasily reduced to afine powder or iiour. `Obvi onsly any moisture condensing upon any oneof the heads 12, 16, or 22 will be' collected in the manner describedVwith reference to the spiral 14 and will be directed into the adjacent`tubularshaft andl carriedpff through the drain pipe 7. f Any moisturecontained in the housing or casingy 24 and which may be driven off bythe heat, will be carried awayjas vaporthrough the Vflue 31.
